Specification of Letters Yatent. Patented NOV, 10,

Application filed December 11, 1913. .Serial No. 865,924,

To all whom it may concern:

Be it known that 1, CHARLES A. Hauswnrrn, citizen of the United States, residing at East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Valve- Lifting Devices, of which the following is a specification.

The present invention relates to a valve spring compressor which is designed for use when dismountingthe puppet valves of same as distended Fig. 4 1s a slmllar view showingthe operating internal combustion engines such as are commonly employed upon automobiles, the object ofthe invention being to provide a device of this character which embodies novel features of construction whereby it may be either hooked into the opening at the top of the valve casing of the engine or fitted upon the cam rod, according to which position of he tool may be most convenient. Further objects of the invention are to provide a valve spring compressor which is comparatively simple and inexpensive in its construction, which can be quickly placed in position or removed therefrom, which will enable the valve spring to be readily compressed preparatory to unseating" and removing the valve, and which is peculiarly constructed so that it can be collapsed and will. occupy but a small amount of space when not] in use.

WVith these and otherobjects in view, the

invention consists in certain novel coinbinations and arrangements of the parts as wlll more fully appear as the, description proceeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention, referenceis to be had to the following description and accompanying drawing, in which Figure 1 is a side elevation of an engine cylinder, showing one manner of applying ig.

to the engine. Fig. 8 is an enlarged plan view of the operating lever, showing the and in osltion for use.

lever in a foldedposition. Fig. 5 is an enlarged perspective view of the fulcrum bar. Fi

a longitudinal sectional view lever. on the line the fulcrum bar in 6 is through the operating 6-6 of Fig. 8, showlng engagement therewith and also showing the *alve rod; and valve spring, portionsrbeing broken away. Fig. 7 is an enlarged transverse sectional view through thespring engaging yoke, the said view being taken on the line 7- of Fig. 3.

Corresponding and like parts arereferred to in the following description and indicatcd in all the views of the drawing by the same reference characters. i i Referring to Fig. 1, the numeral 1 designates a diagrammatic representationuof a conventional form of internal combustion engine, the cylinderbeing provided at the top thereof with the usual laterally. projecting valve casing 2, which has an opening 3 in the upper end thereof, the said opening being normally closed by a suitahleplug, al though this plug is removed preparatory to applyingthe valve lifting and spring compressing tool to the engine. In Fig. 2 the character 1 also designates a diagrammatic representation of an internal combustion engine which has a valve casing 2 at the top thereof. Each form of engine has the usual provided with the valve stems 4 which pro puppet valve, thesaid puppet valves being ject downwardly fromthe valve casings and i are surroundedby the valve springs 5 which are held under compression by suitable nuts or keysl6 at the lower ends of the valve stemsu ln Fig. 2 a cam actuated rod 7 whlch 1s slidably mounted wlthinathe usual guide boss 8 projects upwardlylfrom the base of the engine and is arranged in aline-i ment withthe valve stem i so as to periodically lift the same and unseat the valve in the operation of the engine.

The operating lever-9 of the spring compressing tool, shown more clearly by Figs. 3 and 4%, comprises two sections 9 and 9" which are hinged or pivotally connected at 10. The section '9 of the lever is formed of a pair of spaced strips adapted to receive the fulcrum bar 11 between the same, the

said strips being rigidly connected by suit able fastening members and having the spacing blocks 12 interposed between opposite end portions thereof. A fulcrum pin 13 connects the spacedstrips at an intermedi ate point in their length, and the free ends of the said strips are diverged atfl to'pro engaging yoke 14 is pivotally mounted. Opposite sides of the yoke 1e are providoc with thetrunnions which are; journaled in the arms} of they bifurcated end! of the vide a bifurcated end withinwhich a spring operating lever 9 and are preferably offset from the plane of the yoke, as indicated more clearly by Fig. 7 so as to prevent the end of the valve spring coming into engagement with the lever when the tool is in use.

' formed from a single strip of material and comprises spaced. sides and an outer enlarged and looped end 9*. The spaced sides have a length corresponding to the spaced sides of the lever section 9, and are adapted to receive the lever section 9 between the same, the arms 9 of the bifurcation as well as the spring engaging yoke 14 fitting within the looped end 9 The two lever sections 9 and 9 are pivotally connected at 10 and may be either swung outwardly into alinement with each other, as indicated by Fig. 3, or the section 9 folded rearwardly so as to be completely received within the section 9 as indicatedby Fig. 4'. Vhen in this latter position the lever 9 occupies but a very small amount of space and can be readily packed in a tool case. The outward swinging movement of the lever section 9 is limited by engagement with a stop bar 17 applied to the pivot end of the lever section 9*. The ends of the stop bar are shown as extended laterally so as to embrace and fit against the exterior of the lever section 9*, the said laterally extended ends being riveted or otherwise rigidly connected thereto, as indicated at 18. As previously stated the fulcrum bar 11 is adapted to fit loosely between the spaced sides of the lever section 9, and this fulcrum bar is provided at one edge thereof with a series of notches 19 which are inclined toward one end thereof. Each end of the fulcrum bar 11 is also provided with an opening 20, and one end of the fulcrum bar is designed tobe connected by a flexible member such as the chain 21 to a hook 22. In the present instance. the shank of the hook 22 is returned at 23 for engagement with one end of the chain 21, the opposite end of the chain being engaged by a yoke 24 which straddles one end of the fulcrum bar 11 and has the arms thereof connectcdby a pin 25 passing through the opening 20 of the fulcrum bar. Suitable means such as the cotter pin 26 may be provided for holding the pin 25 removably in position.

One manner of using the tool is illustrated by Fig. 1, in which the hook 22 is placed in engagement with the opening 3 I atthe upper end of the valve casing 2, the

fulcrum bar 11' inserted between thespaced sides of the lever section 9 and a suitable one of the notches 19 broughtinto engagement with the pin 13. The spring engaging hook 14: is properly positioned under the ,valve spring 5 and a downward pressure applied to the looped outer end 9 of the operating lever 9. This results in compressing the valve spring 5 and lifting the valve so that the key or nut 6 can be readily removed.

Another manner of using the tool is illustrated by Fig. 2, in which the chain 21 is detached from the fulcrum bar and hook member and the returned end'23 of the shank of the hook brought into engagement with the opening 20 at the'opposite end of the fulcrum bar 11. The hook 22 may now be placed in engagement with the cam actuated rod 7 or the guide boss for the same, according to the relative size of the hook and engine parts. The fulcrum bar 11 is then swung upwardly from the end of the hook 22 and the operating lever,9 applied thereto substantially as in the previous instance. It will be observed, however, that when the tool is used as shown by Fig. 1, "1

the chain 21 is in engagement with the upper end of the fulcrum bar 11,both the chain and fulcrum bar acting under tension, while when the tool is used as indicated by Fig. 2, the lower end of the fulcrum bar 11 is supported by the hook 22 and the fulcrum bar acts under compression. The tool may be used in either way, according to which is found most convenient, and when not in use the operating lever 9 can be folded together 1;;

and the entire tool amount of space.

Having thus described the invention, what packed in a very small I claim as new and desire to secure by Letters Patent, is
